Application led March 9, 1908. Serial No. 419,861.

To all whom it may concer/n:

Be it known that I, FRANCIS S. Looonnn- MAN, a citizen of the UnitedStates, residing at Upper Fair-ino unt, in the county of Somerset andState of Maryland, have invented certain new and useful Improvements inlowing is a specification.

This invention relates to improvements in spoke sockets and hasparticular reference to a socket of improved construction that may bestamped from a metal blank thus enabling the same to be produced at aminimum cost Without sacrificing strength andv durability. The object ofthe invention is to provide a strong and durable socket that may bereadily attached to a .Wheel to rigidly connect a broken spoke with therim of the wheel and thus enable a quick repair of a spoke to be madevat a minimum cost.

The invention is illustrated in the accompanying drawing inwhich,`-Figure l shows through the riin at one of the broken-off tenaside elevation ofthe improved socket. Fig. 2, a vertical longitudinalsection through the same. Fig. 3, a bottom plan view of the socket. Fig.4, a vertical cross-section thereof. Fig. 5, a top plan view. Fig. 6, aside elevation of a portion oi a wheel rim and spoke with the improvedsocket connecting the two. Fig. 7, a vertical 'cross-section ons, andalso through the socket plate and lower end of the spoke. Fig. 8,illustrates in perspective one of the detached washers or socket plates.Fig. 9, shows aside elevation of a slightly niodiiied form of socketembodying the features ol the invention, and Fig. 10, shows a bottoniplan view of the latter.

Referring to the drawing the. numeral, '1, designates a plate orbaseportionhaving a laterally-projecting tubular socket, 2, which isformed integrally with the base portion and which is open at both itsupperand lower ends. The 'cross-sectional shape lof this tubular socketmay vary to suit the shape oi the spoke it is to receive but in thepresent instance it is circular.

The plate or base portion isslightly curved in a longitudinal directionto vconform to the shape of the rim of' the Wheel to which it is to beattached/andat opposite sides ofthe tubular socket .said base maybeprovided with perfor'ations,.3, for a purpose to be described.. l

At onelengitudinal side edge, the plate or base ortion 1 isv rovidedwith a depending 1 7 l ,zo ilange, 4, and by preference this iiange isprovided with doWnWardly-mchned spaced apart legs, 5, which are providedwith "eriov' rations, 6. T he opposite longitudine side edge of theplate is provided normally with a laterally-projecting flange, 7 which,prior to the application ofthe socket to a wheel rim, is flush with andextends horizontally from the plate or base. This flange, 7, is alsoprovided with legs, 8, having erlorations, Q.

The rim, 10, of the wheeFis provided with the usual mortise indicatedby. the numeral, 11, in Fig, 7, in which the tenon, l2, of the spoke,13, is originally driven. These tenons break 0H in the mortise and thespoke must then either be replaced or repaired and the object of myinvention is to provide a socket which may be readily placed over thelower end of the broken spoke and then fitted by bending it around andsecuring it to the rimthus enabling a quick and permanent repair of thebroken spoke to be made.

'lhetubular socket, 2, may be providedwith inclined slits, 14, whichform tengs, l5, so that after' the socket is in place and con nectedwiththe rim the tangs, l5, may be driven inwardly into the spoke and aid inmaking a rigid connection between the spoke and socket. f

Before the socket and spoke are iitted to the ri-rn, l0, l insert ametal disk or washer, 16, in the lower end ci the socket beneath thespoke so thatwhen in place on the rim the pressure oi' the spoke willnot be directly -upon the broken oil tenen, l2, but will be distributeden the inner circumference of the 'rim'. By inclining the legs, 5, and,t5, l cause the latter to take against the rim at opposite sides ofrthemortise, 1l, where the rirn is soli'd and rigid fastening may be made.inthe device shown in Figs. 9 and i0 socket is formed from a singleplate,-the tubular portion lirst being punched irom one side thereof andthe remaining liat portions of the plate between the horizontal and verm.tical legs, l', and, 18, cut away..

A hase plate or washer' is fitted inside of the tube. adjacent to thelower end so ias to cover the brokenoil tenen in the' wheel rim. ln thisform ol' device both' horizontal and vertical legs are provided withperiorations and the legs being disconnected from each other are auselastic and very readily bent to lit the shape y of the rim to whichthey are to be secured.
